One approach toward optical nanoimaging involves sequential molecular localization of photoswitchable fluorophores to achieve high resolution beyond limit diffraction. Block copolymer micelles assembled from polystryrene-block-poly(ethylene oxide) block copolymers (PSt-b-PEO) are visualized in by staining the polystyrene blocks with spiropyrans (SPs). SPs localized hydrophobic phase exhibit reversible fluorescence on-off switching at alternating irradiation UV and visible light....

All-optical modulation of a spiropyran-based device, integrating the transmittance switching (absorption) and wavelength (emission) visible light frequency induced by alternating UV/visible irradiation is demonstrated. As an alternative to conventional organic transistors, all-optical devices based on SP-PCL have potential utility as single molecular transistors for optical modulation.
We report the design and synthesis of a tetraphenylethene substituted with naphthalimide at 4, 6 positions, named NI-2TPE. NI-2TPE exhibits strong solvent-dependent emission properties combined ICT AIE characteristics in THF-H2O systems. This probe was used directly on test papers to distinguish normal organic solvents using their colours under UV light based its nature. Thanks vinyl group NI-2TPE, we synthesized copolymer NIPAM termed P(NIPAM-co-NI-2TPE). The resulting polymer is highly...
Under the influence of various forces, conflict between Russia and Ukraine is violent changeable. The obtaining battlefield data by conventional means difficult but necessary in order to ensure security, reliability, comprehensiveness. use remote sensing technology can make up for deficiencies methods. By using night-time light data, total number lights built-up areas Ukrainian cities within 36 days outbreak Russian–Ukrainian compiled this paper. Furthermore, dynamic changes at national,...
Abstract We have synthesized a series of fluorene‐based fluorophores, in which central fluorene core has been modified with different peripheral arylene vinylene substituents that are able to activate aggregation‐induced emission (AIE) characteristics. 9,9‐Dioctylfluorene doubly end‐capped at the 2,7‐positions triphenylethene groups, such as 4‐(2,2‐diphenylvinyl)phenyl (F1‐(2,2)‐HTPE) and 4‐(1,2‐diphenylvinyl)phenyl (F1‐(1,2)‐HTPE) were compared tetraphenylethene analogue (F1‐TPE). Both...
